Victoria’s Department of Transport and Planning has launched the Vicmap 1m Digital Elevation Model (DEM), a new offering under its Vicmap Elevation product line.

- Greater ease of use with access to the best-available elevation data through a single mosaic product;
- On-demand access to up-to-date content.
Spatial web services provide terrain, relief, hill shade and footprints, with monochrome surface, coloured and monochrome shaded relief symbology styles. The vertical datum is AHD and the coordinate systems are Web Mercator, VicGRID GDA2020, Geographic GDA2020.
The DEM data itself has 1m-or-higher resolution with vertical accuracy of +/-10cm RMSE. The horizontal datum is GDA2020, the vertical datum is AHD, coordinates are MGA54 and MGA55 and the format is cloud-optimised GeoTIFF. The date range is from 2009 to the present.
Full technical details are available in a downloadable document.
